Building Mechanical Engineer – HVAC & Plumbing Design Lead

Drive efficient HVAC, plumbing, and fire-protection solutions for complex buildings. Apply Revit, energy modeling, and code expertise in a flexible on-site/remote role.

Responsibilities  

- Perform detailed heating and cooling load calculations using Trane TRACE 3D Plus and Carrier HAP.  

- Develop complete HVAC system concepts—air handling units, VAVs, hydronic loops, DOAS—tailored to occupant comfort and energy targets.  

- Model piping, ductwork, and equipment in Revit with clash-free coordination across disciplines.  

- Design domestic water, sanitary, storm, and medical gas networks that meet IPC and NFPA standards.  

- Engineer wet and dry fire-protection sprinkler systems through AutoSPRINK and Pipe-Flo analyses.  

- Select pumps, chillers, boilers, heat exchangers, and controls for reliability, maintainability, and lifecycle cost.  

- Author sequence-of-operation narratives; support commissioning agents during functional performance testing.  

- Validate compliance with IMC, IPC, IECC, ASHRAE 62.1, 55, and 90.1; prepare LEED and ESG documentation.  

- Mentor junior designers, review submittals, resolve RFIs, and collaborate with architects and structural teams.  

- Troubleshoot existing plants—field-verify flows, pressures, and temperatures; recommend retrofit strategies.  

Requirements  

- Bachelor’s or Master’s in Mechanical Engineering.  

- 5+ years designing commercial or healthcare HVAC and plumbing systems.  

- Proficiency in Revit, AutoCAD, Trane TRACE 3D Plus, Carrier HAP, Pipe-Flo, AutoSPRINK.  

- Command of thermodynamics, fluid mechanics, and heat transfer principles.  

- In-depth knowledge of IMC, IPC, NFPA 13, and energy codes.  

- Ability to create sealed engineering documents; EIT required, PE license or ability to obtain within 12 months.  

- Clear written and verbal communication enabling cross-disciplinary collaboration.  

- Authorization to work in the United States.  

Desirable Extras  

- Central plant design experience (chilled water, steam, heat-recovery) for campuses or high-rise towers.  

- Energy modeling with IES-VE or OpenStudio.  

- Familiarity with Digital Twin or BIM 360 workflows.  

- Field commissioning or TAB background.  

- Experience on zero-carbon or net-positive energy projects.
